Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589222, here are decompositions:

103 + 31589119 = 31589222
211 + 31589011 = 31589222
229 + 31588993 = 31589222
271 + 31588951 = 31589222
409 + 31588813 = 31589222
523 + 31588699 = 31589222
619 + 31588603 = 31589222
661 + 31588561 = 31589222

Showing the first eight; more decompositions exist.
